PIPE-CLAMP.

Specification of Letters Patent.

Iatented Jan. 22, 1907.

Application filed November 8, 1906- Serial No. 342.473-

To all whom it may concern:

Be it known that I, RALPH PARKER, a citi- Zen of the United Statesfand aresident of Lakewood. in the county of Ocean and State of New Jersey,have invented a new and Improved Pipe-Clamp, of which the following is afull, clear, and exact description.

This invention is an improved pipe-clamp embodying in its construction aplurality of j aws which are universally adjustable, adapting them tosupport pipes of irregular forms, branch joints, and any kind ofpipe-fitting. The nature of the construction is such that it may befolded to occupy a small compass, enabling the clamp to be convenientlycarried from place to place, and can be manufactured at a comparativelysmall cost, which is a prime feature of the invention.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the preferred form of my invention when inextended rela tion. Fig. 2 is a side elevation, partly in section, of aclamping member which I employ in the construction, said section beingtaken substantially on the line 2 2 of Fig. 1 and viewed in thedirection of the arrows. Fig. 3 is a sectional view corresponding toFig. 2, showing a slightly-modified form, the section bieng taken on theline 3 3 of Fig. 1 and viewed in the direction of the arrows. Fig. 4 isa further modified form of clamping member, which in some cases would bepreferable to the constructions of the clamping members of Figs. 2 and3; and Fig. 5 is a plan of a modified form of strip on which theclamping members are assembled.

The invention comprises two slotted strips 1 and 1 slidably andpivotally connected to gether by a bolt 2, passing through the slots ofeach member, and' having a thumb-nut 3 threaded thereon for clamping thestrips in any desired position of adjustment. As shown in Fig. 1, theslot of each strip extends for almost its entire length, adapting theclamping members to be also adjustably connected through them. One ofthese clamping members, as that connected to the strip 1', isconstructed with a base-plate 4, having a threaded stud 5 projectingfrom its upper face, passing through the slot of said strip I andengaged in adjusted position thereon by l a thumb-nut 6. At oneside ofthe stud 5 a support 7 rises from the plate 4, which supports'coactingpipe-clamping aws 8 through the intermediary of pivoted curved arms 9.The upper end of the support 7 is shaped to conform to andform a bearingfor one of said arms, to which it is adjustably connected by a bolt 10and thumb-nut 11 threaded thereon. A slot 12 cut into this arm 9 admitsof the'arm being slid upon the support in adjusting the clamping-jaws inthe plane in which they are contained. For drawing the clamping-jawstogether a bolt 13 passes through the arms 9 and is engaged on itsthreaded end by a thumb-nut 14, the jaws acting to automaticallyseparate when the nut 13 is unscrewed by reason of a spring 15,

arranged on the bolt between them.

Near each end of the slotted strip 1 are attached clamping members oflike construction to that shown in Fig. 2, except the support 7 andadjacent arm 9 are made as an integral part. Near each end of thebaseplate 4 of each clamping member are provided screw-holes 16,adapting the clamp to be secured in fixed position should it be sodesired.

shown in Fig. 1 it is obvious that the members 1 and 1 may be turnedinto alinement with each other and secured in this osition by thethumb-nut 3, adapting thec am to be conveniently carried from place to pace. In Fig. 4 I have shown a modified form of clamping member whichunder some circumstances might be preferred to the constructions ofeither of the clamping members shown in Figs. 2 and 3. This clampingmember comprises a base-plate 4 stud 5 and thumb-nut 6*, corresponding,res ectively, to the parts 4, 5, and 6 just descri ed, 1 and a support7'", corresponding to the su port 7, the support 7 being preferablystraight and engaged with the lower slotted end of an overhanging arm17, this engagement, which is for the purpose of adjusting the angularposition and elevation of the arm 17, being effected through a bolt 18and thumb-nut 19. The arm 17 has threaded through the extremity of itsupper end a screw 20, swivelly connected with a clamping-jaw 21, whichin operation coacts with an opposed clampingjaw 22, preferably From theconstruction'described and as formed as an integral part of the arm 17.The screw is operated by a hand-wheel 23 or other convenient device.

In Fig. 5 is shown an equivalent device to take the place of the strips1 and 1 in Fig. 1 for adjustably connecting the clamping memberstogether, which consists of two members 24, rigidly connected togetherat substantially the center by a transverse plate 25.

It is evident from the construction as described and illustrated thatthe clamping members of the clamp may be made to assume any desiredangular position with respect to each other, adapting them to supportpipes of irregular forms, branch joints, and any kind of pipe-"fitting.

Although I have described the invention in detail, I regard the preciseembodiment as not material provided the essential characteristics areemployed as pointed out in the annexed claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A clamp comprising two slotted strips, meanspassing through the slots of the strips adjustablyconnecting themtogether, and a clamp member adjus tably connected to each strip throughtheir respective slots.

2. A clamp comprising clamping-jaws pivotally connected together throughthe intermediary of curved arms, a support having its upper end shapedto conform to and form a bearing for one of said arms, and means foradjustably connecting this arm and the support together.

3. A clamp comprising two slotted devices pivotally and slidablyconnected together, clamping members adjustably connected to one of saiddevices through its slot, and a clamping member likewise connected tothe other device.

4. A clamp comprising jaws pivotally connected together through theintermediary of curved arms, a base-plate, a support rising from thebase-plate having its upper end shaped to conform to the outer face ofone of said arms, and means slidably connecting this arm and the supporttogether.

5. A clamp comprising a plurality of clamping members, each comprising abaseplate having a support rising therefrom and clamping-jaws pivotallyconnected together through the intermediary of curved arms carried bysaid support, slotted strips, means passing through the slots of saidstrips adjustably connecting them together, and means passing throughthe slots of said strips adjustably connecting the base-plate of eachclamping member thereto.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

RALPH PARKER.
